Statement of significance:

The vent shaft is a locally prominent landmark and one of only two like structures in Sydney Water's system, which plays an important function to the main western sewer system. The unusual design and reinforced concrete construction is rare for this type of vent on a State level.

Description

Designer/Maker: Metropolitan Board of Water Supply and Sewerage
Builder/Maker: Metropolitan Board of Water Supply and Sewerage
Construction years: 1922-1922
Physical description: A reinforced concrete vent stack built in 1922, octagonal in plan form up to the top of the pedestal from which begins a tapered shaft circular in section with radiating support ribs and three octagonal concrete bands along the length of the shaft. There are neo classical console brackets at the top of the shaft underneath a projecting cornice. The pedestal would be approximately 6m high. A steel entrance door is on the eastern elevation below a rendered hood mould over the door. A galvanised corrugated iron shed is located a metre to the north of this vent stack over the manhole to the main. The location of the site of the vent shaft is directly off Paisley Road and is a triangular site all now paved in concrete. Adjoining development is domestic from the early 20th century, and across the road is the railway line.

Condition overall would appear to be good with some evidence of horizontal cracking towards the upper portions of the pedestal. Some spalling is evident up the shaft. A lightning conductor is located on the southern side of the shaft.

The vent shaft is prominently located and the surrounding topography makes this shaft a landmark for a considerable distance from most vantage points. A lack of large scale and high density buildings contributes to its relatively open visual qualities within this urban environment.

This shaft has a larger scale base than that of the Wentworth Road shaft.

Evidence remains on the street frontage of an original timber gate post some 6 inches squared with original coach bolts and gudgeons still in place. A late 20th century wire cage gate and steel frame is now fitted to the entry of the site.

The shaft and its surrounding fence has little if any immediate streetscape value or give little if any contribution to the surrounding dwellings, although its landmark quality to the broader townscape is most notable.

The paling fence would appear to be late 20th century and not original.

History

Historical notes: The Main Western Carrier which fed into Botany sewer farm was completed in 1897 and encompasses the major crossing of Wolli Creek and Cooks River each by triple barrel 1800 mm dia. wrought iron/steel aqueducts. There are triple barrel brick arch aqueducts at the ends. Soon after construction more sewage was being collected from this newer Western arm than there was from the original Southern Division arm. This is even with allowing for dramatic increase in flow within the first few years of the Southern Division.

The Western Branch Main Sewer which feeds into the Main Western Carrier was completed in stages all the way through to Strathfield. Work was completed on this sewer in 1904.

The section also contains the Croydon (1922) and Burwood (Strathfield) (1919) concrete vent stacks which were built because of damage caused by gases from the then new Homebush Abattoir after it opened in 1916.

In 1888 before the Botany Scheme was even commissioned, Burwood Council had requested a sewage treatment plant for Hen & Chicken Bay on the Parramatta River. They were told by the Government to wait for the Western Suburbs Sewer and the Western Branch Main Sewer is the result of that undertaking. Had the Burwood scheme proceeded, the Western Branch Main Sewer may not have been built in the location it was eventually constructed.

Assessment of significance

SHR Criteria a)
[Historical significance]
The vent has tangible historical associations with the western branch main sewer and through the influence of sewer gases generated from the Homebush abbattoir, an element which has now been removed forever.
SHR Criteria c)
[Aesthetic significance]
The vent is a prominent landmark visually, particularly to the considerable area west and south of the vent stack.
SHR Criteria d)
[Social significance]
It is likely the vent stack holds some value to the local community in its function and landmark value.
SHR Criteria e)
[Research potential]
The vent plays an important function in the servicing of the western branch main sewer.
SHR Criteria f)
[Rarity]
Regarding its design and construction it is rare on a State level and one of only two in the Sydney Water system.
SHR Criteria g)
[Representativeness]
In terms of vent function alone, it is representative of the function it has played in the operation of sewer systems.
Integrity/Intactness: Considerably intact.
Assessment criteria: Items are assessed against the PDF State Heritage Register (SHR) Criteria to determine the level of significance. Refer to the Listings below for the level of statutory protection.

Recommended management:

Manage the place and its significant components in accordance with the Heritage Council State Owned Heritage Asset Management Guidelines and the Minimum Standards of Maintenance and Repair in the NSW Heritage Regulations. Manage significant site elements in accordance with a Conservation Management Plan (CMP). If no CMP exists, consult with Asset Management Commercial Services with respect to commissioning a CMP. When commissioning a CMP, do so in accordance with the Model Brief for CMPs available on ConnectNet. Seek endorsement of the CMP from the Heritage Council of NSW. Works undertaken in accordance with a Heritage Council-endorsed CMP do not require further approval under the NSW Heritage Act. Involve heritage professionals as required under the terms of the CMP, or as otherwise determined necessary. Review CMP every 5 years or in a major change of circumstances, whichever is sooner. Review of a CMP should only be undertaken following consultation with Asset Management Commercial Services . When commissioning a CMP review, do so in accordance with the Model Brief for CMPs available on ConnectNet. Where no CMP is in place, or where works are outside the scope of the existing CMP, assess heritage impacts of proposed works in accordance with Sydney Water Environment Impact Assessment guidelines (e.g. undertake a Heritage Assessment and/or Statement of Heritage Impact as required, obtain Heritage Council approval as required). Consult with the Heritage Manager, Environment and Innovation, when major works are planned which affect items of State heritage significance. Undertake archival and photographic recording before major changes, in accordance with Heritage Council guidelines. Lodge copies of the archival record with the Sydney Water Archives and the NSW Heritage Office. Where the item is listed in a Local Environmental Plan Schedule of Heritage items, determine if works are exempt from approval under the LEP provisions. Where works are not exempt, obtain necessary approvals from the local council, in accordance with SWC EIA Guidelines.
